A ligand that can bind to a receptor, alter the function of the receptor, and trigger a physiological response is called an agonist for that receptor. Agonist binding to a receptor can be characterized both in terms of how much physiological response can be triggered and in terms of the concentration of the agonist that is required to produce the physiological response.
A signaling molecule. The term ligand is used for a molecule that specifically binds to another molecule, often a larger one. Ligand binding generally causes a receptor protein to undergo a change in shape.For many receptors, this shape change directly activates the receptor, enabling it to interact with other cellular molecules.For other kinds of receptors, the immediate effect of a ligand binding is to cause the aggregation of two or more receptor molecules, which leads to further molecular events inside the cell.or many receptors, this shape change directly activates the receptor, enabling it to interact with other cellular molecules.
